DS18 ZXI6.4D ZXI High Excursion 6.5" Car Audio Subwoofer 600W Watts 4-Ohm DVC Quad Stacked Magnets

Do you want more excursion, more thumping power, and to shake everyone's mirrors around you?

DS18 has the perfect subwoofer to satisfy all your bass head needs in the newly designed ZXI6.4D high excursion subwoofer. This monster mini sub packs a whopping 1.5 inch coil made to withstand high amounts of power with the utmost efficiency while producing thunderous distortion free bass.

This sub has a much lower than normal FS so it can be used in larger boxes with lower than normal tuning. Not only will this subwoofer slay the lows, it is versatile enough to also play higher frequencies with authority.

The ZXI subline is a great high excursion line of subwoofers that both handle great power and give you smooth clean bass while playing ultra low frequencies but also shine in the higher bass range as well. These subs work great in both sealed and ported boxes giving you many options for placement in any vehicle.

This 6.5 inch model comes dual 4 ohm and comes with a 1.5 inch voice coil that handles 300w RMS and 600w max power. The large foam surround and pressed paper cone works greatly together to deliver smooth crisp bass that can be heard strongly throughout the vehicle giving you an amazing bass experience.

Highlights 

  • Large foam surround giving great high Xmax and bass precision while keeping great cone control when the subwoofer is close to maximum power.
  • Great power handling of 300w RMS and 600w max through a high strength 1.5 inch aluminum voice coil.
  • Very strong stamped basket with show quality DS18 logos on the frame, magnet boot, magnet, and dust cap.
  • Designed to give crisp and clear bass in any vehicle and can be used in sealed and ported boxes.

It really works. Cleaner, quieter, smoother operation.
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
This is the most amazing oil I have ever used. As a previous mechanic and current auto enthusiast, I am very picky about what I use in my vehicle. I tried this on a car I planned on trading in for about a year before getting rid of it and it really made a difference in quieting down the lifters and valve train. Looking internally to the engine I found that this does clean and dissolve varnish internally while also retaining its viscosity. I was impressed by the improvement in how smoothly it made that car run until trading it in. I've been using it in my new to me 20 year old used car I bought which has low mileage and runs great. Using this oil has only made it run better. Quieter, smoother, etc. I have used RP, Mobil 1, Pennzoil, and more. This one is my new number one that I plan on sticking with for the life of my vehicle.

Simply put, it’s a miracle product
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
There’s a reason this product won the best consumer product of the year, 40,000 customers voted on this product as the most innovative product of the year for car care. Personally it has stopped my 185,000 mile, 16 year old Subaru EJ253 engine from consuming/burning oil in just 2 3,000 mile interval oil changes. I was previously burning about a quart of oil every 1,000 miles before using the Valvoline restore and protect and it has already done its job and then some. Not only have I stopped consuming oil, I’ve seen roughly a +3mpg increase compared to the times I’ve used and tracked MPG while using Shell Rotella T6 and Pennzoil Ultra Platinum; it doesn’t end there either as I regularly check my engine oil dipstick out of habit because the car used to burn oil and I had to stay on top of the oil level. Upon checking my oil level at 1,000 miles into the second oil change I was shocked to see how clean the Valvoline oil was on the sides of the dipstick, using other oils and checking them at that interval has always had my oil looking quite black and dirty just 1000 miles after a change, this was not the case with the restore and protect; it came out at 1000 miles looking very clean, translucent and not discolored. I can’t recommend this product enough, especially at the price point compared to competitors; I will always have a jug of this stuff in the garage.

Incredible motor oil !
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
I've used this in my 2014 Buick Encore with 91k miles on it for 2 oil changes and the results are extremely impressive. The engine in the 'ole gal is noticably quieter and my gas milage is definately improving. I switched from Mobil 1 to this oil based primarily on reviews and I'm glad I made the switch. This vehicle is not only my commuter car (80 miles per day), but it's my "winter" vehicle so it sees some temperature extremes. This oil is remarkable ! Time will tell, but I definately recommend it.

Good! I would buy this again if needed.
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Good! I would buy this again if needed. The best oil to use in a KIA, IMO. Keeps it clean and might help prevent oil burning. Your KIA needs the best oil you can feed it. They are known for failing engines so why not give it the best, especially if its out of warranty like mine!

USE THIS 3 yr old-10yr old cars But it is not for use for classic muscle car-flat tappet cams
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Valvoline has come up with a tested, amazinng engine oil for not the newest cars..but for cars say 3-10 years old that may have some varnish-sludge build up..works slowly enough over time so it doesnt suddently clog the filter, but DO change oil and filter at 3500, not more. In fact 3500 to 4K max for ANY car, any time. DO NOT go longer as some mfg or oil say you can. Tests show that sludge builds up. This oil is NOT for classic muscle cars with flat tappet cams.
